A search warrant is a legal document issued by a judge or magistrate that authorizes law enforcement officers to search a specific location for evidence of a crime
In the United States, the issuance and execution of search warrants are governed by the Fourth Amendment, which protects against unreasonable searches and seizures. To further this goal, law enforcement must demonstrate sufficient evidence that a crime has been committed and that evidence of that crime is likely to be found in the location specified in the search warrant.
